I just bought my first road/touring bike, which I'm very excited about (a dramatic shift from the oversized bmx bike I've been riding for 10 years). For $700, I picked up a 2003 Jamis Quest (what could be sexier than chrome!), never touched pavement, with all 105 parts.

Well almost all 105. It was supposed to come with Shimano 105 STI Dual Control Shift Levers, but they were somehow lost in the 2 years the bike spent in a box. The shop kindly upgraded me to Ultegra, and my first spins have been like buttah.

But here's my problem: I can't engage the big ring with the index shifting. Is this just bad tuning on the part of my LBS, or is there a chance that I have Ultegra shifters meant for a double? I just wanted to be informed before I cart the thing back to my not so local LBS. Any tips would be helpful.
